INTRODUCTION :

Disclaimer:
The following movies are rather rough. I prefer to spend time on development of more 'apps' --- and I seem to have a never-ending stream of ideas for more apps.

Download speeds:

After clicking on the following movie files, they will download at a rate around one Megabyte per second (or more), if you are on a high-speed Internet connection (like cable or fiber-optic). At least, if you are in the U.S., that statement should be correct --- especially at low-Internet-traffic times of the day (like 2 A.M. Eastern U.S. time).

Since the movie files are on the order of 8 to 20 Megabytes in size, they can download within about 10 to 25 secs --- and then start to play --- if you have the proper software.


Movie types:

To help assure that you can play at least one of the movies, at least one of the several movies will be available in different formats (3 different 'container' formats - MP4, AVI, and FLV).

Image sizes:

Each movie will be available in a small size (640x480), which is just large enough to read the text in the screen images. In other words, 640x480 is just about the smallest I can make the movies and still have the text in the screenshots be readable.

Some of the 'demo' movies are presented in a large size, 1024x768 pixels --- as well as the small size.


Download option:

If you have trouble playing a file in a movie player 'plug-in' of your web browser, you could right-click on the movie links below and choose to download the movie files to your local storage. Then you can experiment with playing the files with a variety of movie players (QuickTime, Mplayer, Windows Media Player, Flash plug-in or player, video editors) on your computer.


    2011may17 PLAYABILITY NOTE:
    I have been able to play all the movies below on an MS Windows machine in the lobby of a hotel. The MP4 files played in a Quicktime plug-in (version 7.6.9) in the MS Windows web browser. The AVI file played in a Windows Media Player plug-in (version ?12?) in the browser.

    I have verified that the MP4 and AVI and FLV movies play on my Ubuntu Linux 9.10 system, using 'ffplay' and 'mplayer' --- as well as GUI offshoots of 'mplayer' such as 'gnome-mplayer', 'gmplayer', 'smplayer', and 'Totem' --- and a web browser plug-in, 'gecko-mplayer'.

    I am awaiting word from friends with Apple computers (Mac desktops or laptops, iPads, iPhones) whether they can play the MP4 movies on their Apple systems. [2011May19 update: I got word that the smaller 640x480 MP4 files are playable on an Apple iPad. I am still trying to get someone to try the larger 1024x768 movies on an iPhone or iPad, to find out how those devices handle the large movies.]

    I know that the MP4 files would NOT play in an old Quicktime plug-in (version 6.5, last copyright 2004) on a 2007-era MS Windows XP machine. And the AVI file would NOT play in an old Windows Media Player plug-in (version 10, last copyright 2004) on that XP machine, although the audio would play (video was black).

    So recent versions (2008-plus) of Quicktime and Windows Media Player will probably be needed.


Video-audio-container formats:   (more on this in a section below)

When I find what formats (and image sizes and frame rates and audio parameters) are best to use --- for playability by people's software and for a good compromise between quality and speed of downloading, then some of these movies may be re-done ... in the 'popular' formats and with better video-audio parameters.

Since better compression methods (for video and audio) are evolving, I may eventually convert some of these movies to 'more modern' video-audio-container formats.


Audio issues:   (my bad)

Sorry about the 'uh' pauses in these 'DEMO' movies. I was winging it, without a script. And I did only one 'take' of each movie.   .   .   . And I just say 'uh' a lot.   :-)

    2011 Jun 09 UPDATE:
    I find that I have a hard time doing non-scripted talking throughout a non-trivial demo without supplying lots of uh's and and's (which, I now realize, has been a life-long bad habit), so ... I edited the audio of the 'INSTALL-DEMO' movies, before posting them here, to remove the uh's.

    Further, I went back and edited the audio in the 'APP-DEMO' movies, to 'squash' uh's out of the and-duh's, the thuh-uh's, the pause-uh-pause's, and the pause-uh-pause-uh-pause's --- as well as squash a few other lung/throat/tongue/teeth-generated extraneous sounds, noises, and 'stutterances'.

    If I generate any more movies, I intend to do a better job on the audio --- or edit the audio before posting the movies here.


Volume level:

The audio level may be low in most of these movies. You may have to boost the volume in the speaker control of your movie player.

Audio parameters:

Besides some artifacts introduced by the audio editing, the audio in these movies may be a little 'scratchy' because I used rather minimal audio parameters --- 96k bits/sec, 22050 Hz max, monoaural ... rather than higher quality parameters like 192k bits/sec, 44100 Hz max, stereo. I did this to reduce the size of the movies, for faster downloading.

    (The audio accounts for more than half the size of these movie files. The video portion of these movies is probably relatively small because the only change between many of the frames is simply the movement of the mouse cursor. Hence the video stream can be compressed a lot.)


A favored video container format:

The MP4 format, used in most of the movies below, is like the Apple MOV format. You can probably play MP4 movies in a recent Quicktime movie player on Apple and Microsoft operating systems. Mplayer should work on Linux systems, if H.264 (video) and AAC (audio) decoders are available.


Enough of this introduction. Below are some movies --- 'install demo movies' and 'app demo movies'.

FE INSTALL demo movies :

< Go to Top of Page, above. >


INSTALL of 'feNautilusScripts' :

How to INSTALL, TAILOR, and TEST the feNautilusScripts subsystem
|
(640x480 movie image size, 20min 34sec, ~15Meg -
H.264 video and AAC audio in an MP4 container)

The TAILORing shows how to set the VIEWER/EDITOR vars. The TESTing exercises one of the scripts categories, LinuxHELPS. The TESTing shows how to use several of the LinuxHELPS --- taking advantage of some powerful features of 'xpg'.


INSTALL of FE 'xpg' :

How to INSTALL and SETUP the FE 'xpg' subsystem
|
(640x480 movie image size, 11min 07sec, ~8Meg -

INSTALL of 'feAppMenus' :

How to INSTALL the 'feAppMenus' subsystem
|
(640x480 movie image size, 12min 17sec, ~10Meg -

Alternatives. In case you can't play the MP4 format, try these ---
FLV (flash) or AVI containers.

Some more demo movies of using FE Nautilus Scripts could be made --- for some of the scripts in the menu categories such as

  • AUDIOtools
  • CHANGEfiles
  • EXAMINEfiles
  • FILESlists
  • FINDlists
  • IMAGEtools
  • SPACElists
  • TERMtools
  • VIDEOtools
  • etc.

. . . but I may never get around to it, because I have too many computer projects that take higher priority.


DEMO of 'xpg' (and 'feNautilusScripts') :

Demo of 'xpg' (and an FE Nautilus Script - findSTRING)
|
(640x480 movie image size, 8min 44sec, ~7Meg -

Some more demo movies of the feAppMenus subsystem would be nice to have --- for the 'EditVARs' option, to change

  • fonts
  • colors
  • geometry ( of widgets / windows )
  • apps ( readers / editors / other )

to more-completely describe tailoring possibilities of the feAppMenus subsystem.

ON VIDEO-AUDIO-CONTAINER FORMATS for movies :

Here is an introduction to 'containers' for video and audio (Wikipedia) --- with links to info on coding formats for video and audio.

Often movie files are referred to by the 'container' name, without specifying the format of the video and audio streams within the container.

One man, who makes movie files for others and who is often frustrated that they specify a container format but no format for the video and audio, explains it this way.

The container is like the bread on a sandwich. If you ordered a sandwich you would not simply specify the bread that you want, like 'whole wheat' (the 'container').

You would also need to specify the contents of the sandwich ... such as peanut butter and jelly ... or turkey and lettuce ... or ham and cheese (video and audio).

Therefore, above, I have given the 3 formats that help more completely specify the coding of each movie file. (There are still other factors, such as frame-rates, bit-rates, audio-frequency-range, and number-of-audio-channels, that specify the coding even more completely.)


For some indication of the combinations of these 3 formats (video-audio-container) that are frequently used, this web page on example movie file formats provides a list of commonly found movie format combinations --- via movies sampled from web page links, YouTube, etc. That page discusses the confusion in 'type-casting' of movie files.
